@MacUpdate admins, Purebasic 5.50 has been available since July 2016 (http://www.purebasic.com/news76.php)
Also, the web version, SpiderBasic, is now at 1.40 (https://www.spiderbasic.com) - I notice there is no entry for it at macUpdate
Having had a chance to play with PB a bit now, I can say that it is a lot more powerful than might be expected. It's chock-full of functionality and yet still generates small and fast executables across three platforms. It's more like C with a Basic syntax than old school Basics. Pointers, structures, modules, events, etc etc make this a useful addition to your dev toolbox.
Although some of the functionality can be a little clunky, such as the JSON commands, the decent Help and helpful online community makes getting solutions to probems quite easy to achieve.
My one tip would be to avoid the built in form editor and use the new XML-based dialog library which is far more flexible.
As mentioned, there is a web version available, SpiderBasic (sold seperately) which I have used to build new user interfaces to our business APIs -works a charm.
